Herald & Review (Decatur, Ill., Dec. 16) – Researchers are beginning to explore the possibility of capturing and storing carbon dioxide below ground at more sites near Decatur than the initial area of focus surrounding the main Archer Daniels Midland Co. complex. A site of interest for further evaluation is the Forsyth oil field north of Decatur, says Sallie Greenberg, the associate director for energy research and development with the Illinois State Geological Survey, which is part of the Prairie Research Institute at Illinois.
